Urbanization, industrialization, and informatization raised quality of life in modern society. However, many people face with social maladjustment phenomena of human alienation and loss of true self due to mechanization, competition and stress. To alleviate the social maladjustment, people should look for their true self and the self. Drinking tea may play an important role in bringing your true self and the self and be a vehicle for them to meet in daily life. Therefore, this study uses the standard web protocol technology to popularize the True Self Tea Ceremony which helps to enhance true self and self-respect. The True Self Tea Ceremony uses the basic utensils. The paper proposes the popularization of the True Self Tea Ceremony using the standard web protocol technology. Using the standard web protocol technology enhances the accessibility of users.

Water is a necessary condition of plants, animals and human. The state of the water shortage, that drought is globally one of the most feared disasters. This study was calculated target standardized precipitation index with unit of region for judgment and preparation of drought in consideration of the regional characteristics. First of all, Standardized Precipitation Index (3) were calculated by monthly rainfall data from rainfall data more than 30 years of 88 stations. Parametric frequency and nonparametric frequency using boundary kernel density function were analysed using annual minimum data that were extracted from calculated SPI (3). Also, Target return period sets up 30 year and target SPI analysed unit of region using thiessen by result of nonparametric frequency. Analyzed result, Drought was entirely different from severity and frequency by region. This study results will contribute to a national water resources plan and disaster prevention measures with data foundation for judgment and preparation of drought in korea.

The ISO standard specifies the diameter of the gas introducing tube to be definitely 1/10 of the chamber inner diameter of the standard test dome which is used for evaluating the performance of vacuum pumps. Because the inner diameter of the test chamber should not be less than the intake diameter of the vacuum pump, the tube diameter would be even 100 mm if fitting to a very large vacuum pump. Though such a thick tube can be accommodated in a large test dome, it is worthful to investigate whether a thicker tube is helpful or adverse for making more accurate measurements. In this paper it is discussed if there is an optimum tube diameter by comparing the isotropicity of particles emanating from the tube and that of particles entering the orifice.

The EPMA analysis for CHIME dating requires standard materials, which include nuclear fuel materials that are rare and sensitive to handle. Any laboratory that does not meet these standards has had difficulties adopting the CHIME dating method. We have developed a working standard technique for CHIME dating to prepare standard materials without use of nuclear fuel materials. Mineral samples, such as small pieces of monazite that are homogeneous in X-ray intensities, are calibrated using well-characterized primary standards in one laboratory. Once this procedure is done, they can be readily usable as working standards in the other laboratories, only with measurement of X-ray intensities. This method is applicable in preparing standard materials for both chemical compositions and determination of X-ray interference correction factors, and it is independent from chemical composition of mineral standard.

For the study of the effects of low gamma-irradiation on malt enrymes, barley seeds were irradiated by Co-60, with 10, 100, 1,000 and 10,000 rads respectively. The experiments on the germinated green malt were resulted as follows. (1) By the low doses below 1,000 rads the fresh weights of green malts increased but at the hgih doses of 10,000 rads they decreased. (2) In all doses ${\alpha}$-amylase activity and saccharifying ability were expedited, showing the increased effects of 23-69% and 87-178% respectively and their peaks at 100 rads. (3) Protease activity showed almost no changes ein the low doses below 1,000 rads and decreased remarkably at the high doses of 10,000 rads. (4) Reducing sugar contents of green malts were decreased, particularly in 100 and 1,000 rads. (5) Soluble protein contents of green malts were increased in all doses and had their highest value at 100 rads.

This study was carried out to evaluate the proper application amount of anaerobic digestion waste water and the environmental influence on rice. The waste water collected after methane fermentation process of pig manure was used as a liquid manure. Liquid manure 100%+chemical fertilizer 30%(LM 100%+CF 30) treatment was the most favorable at all growth stages of rice. The LM 100%+CF 30% treatment was applied to 100% amount of liquid manure which was correspond to the same amount of nitrogen for the standard application amount on rice, with adding 30% amount of chemical fertilizer(urea) at tillering stage. The yields of rice in the treatments of 100%(LM 100%) and 150% amount(LM 150%) of liquid manure were similar or a little higher than NPK treatment but LM 100%+CF 30% treatment was less than the NPK treatment due to the increase of straw weight and plant lodging. In periodic changes of the $NH_4-N$ and $NO_3-N$ contents, the LM 70%+CF 30% treatment in paddy soil was the highest in all treatments. The NPK and the LM 100% treatments in irrigation water quality were higher than other treatments. In infiltration water quality, $NH_4-N$ content was leached out much in the LM 150% treatment and $NO_3-N$ content was in the LM 100%+CF 30% treatment. The proper application amount of anaerobic digestion waste water as a liquid manure must be to analyse the nitrogen content of the waste water and to apply the same amount of nitrogen for the standard application amount on rice.

This study was conducted to ameliorate the productive performance of Hanwoo cow using hill pasture grazing system. Twenty seven animals aged 9 were designed to divide with 3 groups which were Control (restricted concentrate and hay for 5 months), T1 (restricted concentrate and pasture grazing ad libitum for 5 months) and T2 (restricted concentrate, 30 g/head of mineral nutrients and pasture grazing ad libitum for 5 months). Average daily gains increased higher in the order of T2, Control and T1. The conception rate of Control, T1 and T2 after artificial insemination during post-grazing period were 88.9%, 100%, 100%, respectively. In conclusion, the results indicated that hill pasture grazing system might enhance not only the productive performance of Hanwoo cow but also profit for conventional feeding system.

This experiments were performed to investigate the temperature effects, which caused by the various types of collecting trap treatments, during the overwintering period of pine gall midge larvae, on the peak adult emergence time. And the following results were obtained. 1) The maximum temperatures inside of the collection traps were significantly different each other, and the vinyl cage showed the highest degree which highering $15^{\circ}C$, and standard cage, cage-50 and funnel trap highering $3-12^{\circ}C$ in monthly average comparing to control. 2) There was no significant difference among the treatment in minimum temperatures, during the overwintering periods of larvae. 9) The peak adult emergence time were May 15 in vinyl cage plot which shortened 20 days and both standard cage and cage-50 shortened 14 day than that of control. 4) The funnel type trap treatment delayed 6 days of the peak adult emergence comparing to control, in spite of the treatment showing higher maximum and cumulative temperatures than the control plot. 5) The decadal maximum temperatures of middle part of December and March were significantly correlated with the shortening of the peak adult emergence date.

기존 망관리구조와 달리 차세대 망관리에서 요구되는 새로운 개념으로는 QoS관리, 망관리 분산화가 고려된다. 이에 핵심적 차세대 망관리구조의 핵심요소는 SLM(Service Level Management), TMN(Telecommunication Management Network)이다. 선진국을 중심으로 TMN 관리표준 업무처리 절차를 수립하여 이를 시스템화하여 솔루션으로 공급하고 있으나, 국내실정에 적합하지 않으며, 특히 전력분야에 적합한 전력통신망 통합관리를 위한 체계적인 표준 업무처리전차에 대한 개발이 필요한 실정이다. 전력 산업분야의 전력통신망 통합관리를 위한 표준절차의 부재로 기존 투자된 시스템의 효율성을 향상함에 있어 어려움을 가지고 있을 뿐 아니라 향후에 확장 도입되는 Management 솔루션에 있어서 불필요한 중복투자 가능성이 상존하고 있으므로 체계적이며 표준화돤 관리체계의 개발이 필요하다. 본 논문에서는 전력통신 설비별로 운용중인 다수의 NMS 통합 및 유지관리용 전산설비와의 유기적인 결합을 통한 최적의 전력통신 망 종합관리체계 구축방안을 제시하기 위해 전력연구원에서 수행하고 있는 연구과제와 관련하여 차세대 전력통신망 관리방안에 대해 기술하였다.
